Different car owners have the different requirements of the car DVD, some focus on appearance, some focus on the sound quality, some focus on the function and some focus on cost. Therefore, when buying car DVD player China, we should make comprehensive comparison according to our preference in the same grade products, judging which the specific product is best for you.
Check whether the size of car DVD is suitable for your car
The first step to buy car DVD is to determine whether the size of the machine is suitable for your car. As regards to car DVD panel size, there are conventional 1DIN and 2DIN two categories. Generally small vehicles use 1DIN size products, occupying a standard CASE. The size of the 2DIN instrument panel is relatively large; many products look more luxurious, so they are used for commercial vehicles. Some medium vehicles need to transform if they want to install 2DIN size devices. It is recommended that the average small vehicle users try to use the 1DIN standard size equipment, so that the installation and replacing the existing deck will be more convenient. Some car owners choose a single spindle car DVD player with no screen and a single spindle retractable display, which first requires the installation space being a dual-spindle, but the heat dissipation of two single-spindle machine is relatively larger than the single tablet with a screen, we recommend using a single tablet with the screen.
Determine the structure and level of car DVD manufacturers
The second step to determine the structure and level of car dvd supplier according to your budget and needs. Car DVD players are divided into single disc and multi-disc from their own structural characteristics. The multi-disc DVD player is available for front multi-disc DVD player and rear disc DVD player with "backpack". Ordinary single-disc DVD player has a simple structure and the price is relatively cheap, which is suitable for middle and low car. The benefit of multi-disc player is the convenience to change discs, but because there needs to have a cable between the disc box and DVD host, which will have some loss of signal and will have a certain impact on the interference of the car. Of course, high-end CD changer will use digital processing at all costs, so their prices have soared. In fact, for our general car owners, manual changer is not a trouble, and can save the cost of a thousand dollars, so the single disc car DVD player is a cost-effective choice.
Weigh the performance and functionality of car DVD players
The third step is to weigh the performance and functionality of the different grades of products. If you are music fans and like to listen to some of the large dynamic song, then you can care about the output features and sound quality of the car DVD car dvd player supplier. Car DVD players output power is related to the music dynamic performance capacity. Generally the nominal per channel output power of DVD player is between 30 ~ 55W, and 4-channel output, which can directly drive the ordinary speaker. Some high-end car DVD itself does not contain the amplifier, requiring external dedicated in-car amplifier. In general, external professional amplifier performance is superior to the DVD player built-in amplifier unit and the power is larger. Brand name car amplifier is equally valuable. It is necessary to update the car audio and line if you want to have a good effect.
